Galv water pipe is not over dear, doesn't need much support, and easy to plumb 1/2" fittings onto.
May be more prone to condensation though, if you are spray painting.

have galvanized piping run in one shed and the john guest in another, the JG stuff is dearer when everything is counted up but looks pro.
i used the flexi jg in a duct and used the blue alu as drop lines.
if you were going all flexi its not dear really. its quick to put up compared to threadding and mounting the 1/2 galv pipe.
